  49 [+NAME?bldenv - spawn shell for interactive incremental OS-Net
  50     consolidation builds]
  51 [+DESCRIPTION?bldenv is a useful companion to the nightly(1) script for
  52     doing interactive and incremental builds in a workspace
  53     already built with nightly(1). bldenv spawns a shell set up
  54     with the same environment variables taken from an env_file,
  55     as prepared for use with nightly(1).]
  56 [+?In addition to running a shell for interactive use, bldenv
  57     can optionally run a single command in the given environment,
  58     in the vein of sh -c or su -c. This is useful for
  59     scripting, when an interactive shell would not be. If the
  60     command is composed of multiple shell words or contains
  61     other shell metacharacters, it must be quoted appropriately.]
  62 [+?bldenv is particularly useful for testing Makefile targets
  63     like clobber, install and _msg, which otherwise require digging
  64     through large build logs to figure out what is being
  65     done.]
  66 [+?By default, bldenv will invoke the shell specified in
  67     $SHELL. If $SHELL is not set or is invalid, csh will be
  68     used.]
  69 [c?force the use of csh, regardless of the  value  of $SHELL.]
  70 [f?invoke csh with the -f (fast-start) option. This option is valid
  71     only if $SHELL is unset or if it points to csh.]
  72 [d?set up environment for doing DEBUG builds (default is non-DEBUG)]
